51單片機制作的八階流水燈

ID:1051855 · 發表于 2022-11-14 12:57

女朋友的生日要到了，絞盡腦汁想送一個有意義的禮物。
后來在網站上看到了這個八階流水燈，感覺非常漂亮，準備做一個送給女友。
受限于網絡資料有限，浪費了不少的錢還浪費了不少的精力。
在這里分享給各位，希望能給大家帶來一點幫助。

自己寫的程序，使用了8*8*8個led小燈。
既可以使用220V電源供電也可以使用充電寶供電。

主要使用的是74hc595芯片的聯級，當時為了找合適的芯片可是費了好大功夫。

真的是從o開始學的，推薦學習視頻https://www.bilibili.com/video/B ... story.content.click
